Abstract

Phytoremediation is a low cost soil remediation technique which had made no widereaching. Within the instant phytoremediation technique using timber species have been rarely reported. This study is intended to examine a timber species i.e. Acacia mangium ability to extract Zn Cu and Cd from contaminated soil. A field experiment was conducted on a sewage sludge disposal site for a duration of 12 months. Results had shown that A. mangium aboveground biomass accumulates 200mg/kg of Zn 40mg/kg of Cu and 2.0mg/kg of Cd at the end of experiment. It is estimated that 339t/ha of aboveground biomass would be required in order to remove 79.8kg/ha of Zn 1 173 t/ha biomass for 46.9kg/ha Cu and 1 165t/ha biomass for 2.33kg/ha for Cd to pass an acceptable safe level and this exercise can be achieved within 3 years. In a 10-year period it is estimated that 25 300m3 of timber would cultivated thus offers a rewarding substantial income of approximately USD 1.6 million. This evident postulate that phytoremediation is a commercially viable remediation approach and ought to be widely applied as a sustainable answer for contaminated soil remediation.
